意を促していた。2. Description of the Related Art Conventionally, there is known a device equipped with a backup storage battery in addition to a commercial power supply. In such a device, it is usually driven by a commercial power source, and in the case of a power failure, the power source is switched to a storage battery and driven. Therefore, when the storage battery is loaded in the device and shipped,
If left unplugged from the power outlet, a minute current flowing through the control circuit, load, etc. will reduce the electric capacity of the storage battery and cause the storage battery to become over-discharged. If the storage battery is over-discharged, there is a risk that the storage battery will leak liquid and the performance and life will be extremely deteriorated. To prevent this, the storage battery must be packaged separately, or tapes must be inserted at the connection between the storage battery and the device before shipping, and the storage battery must be packed separately when the user first uses the device. The storage battery and the device were energized by taking them out and loading them into the device, or by pulling out and peeling off the tape when using the device. In addition, even after starting the use in this way, the instruction manual warns that the storage battery will be removed from the device again if the power outlet is not used for a certain period of time.

Moreover, if the storage battery is removed when the power outlet is removed, the device may be damaged later due to the leakage of the storage battery, or the storage battery may deteriorate and the storage battery needs to be replaced early. An object of the present invention is to solve the above problems and to prevent overdischarge of a storage battery even when the commercial power supply is stopped for a long time while the storage battery is still loaded.

の使用に備えてスタンバイする。When the commercial power supply is turned on, the rice cooker with a storage battery is first stepped down by the transformer 22 and then the rectifier 23.
Is converted into direct current, and a voltage is applied to the booster circuit 11 via the power source changeover switch 5. The power source changeover switch 5 is connected to the A terminal side only when the voltage (V CC2 ) is applied,
It is a relay that returns to the B terminal side when it is not applied.
When connected to the terminal side, to the storage battery 3 side, the booster circuit 11
Switch the circuit to. Therefore, the commercial power source side is always connected while the commercial power source is turned on. Boost circuit 11
Raises the applied voltage (V CC2 or storage battery voltage) to a voltage (V DD ) sufficient to operate the microcomputer 9 and the load 1. The reason why the booster circuit 11 is provided is that the operating voltage is high in an ordinary microcomputer, so it is necessary to change the specifications of the storage battery to raise the voltage or boost the low storage battery voltage, but the specification change cost of the storage battery is This is because it is more expensive than the additional cost of the booster circuit. A method of changing the specifications of the microcomputer to reduce the operating voltage of the microcomputer can be considered, but the microcomputer is expensive and not practical. When the commercial power supply is stopped by disconnecting the power outlet or the like, the signal of the power source switching circuit 4 connected to the commercial power source unit 2 is stopped and the power source switching switch 5 is switched to the storage battery 3 side. Then, the voltage of the storage battery 3 is boosted by the booster circuit 11 and applied to the load 1 and the microcomputer 9. At the same time, the voltage (2.4 V) of the storage battery 3 is
The signal of the storage battery voltage detection circuit 6 is monitored by the microcomputer 9, and when it is determined that the detection signal has dropped to a predetermined voltage (for example, 2V), the switching unit (not shown) of the storage battery 3
The switching element 7 provided between the power supply switch 5 and the power switch 5 is turned off to disconnect the storage battery 3 and the load 1. The power supply (V DD ) of the microcomputer 9 is also turned off and does not recover until the commercial power supply is turned on again. The microcomputer 9 is completely stopped, and the minute current consumed in the so-called sleep mode does not flow. Therefore, in this state, the storage battery 3 loses power consumption due to discharge. When the commercial power source is turned on again, the power source changeover switch 5 is switched to the commercial power source side (from the B terminal side to the A terminal side) by the signal of the power source switching circuit 4, and the booster circuit 11 is also activated to generate a voltage (V DD ) to the microcomputer 9. Is applied to restart. At the same time, charging of the storage battery 3 is resumed from the charging circuit 21, and when the voltage of the storage battery 3 returns to a predetermined voltage, the switching unit of the microcomputer 9 turns on the switching element 7 to turn on the storage battery 3
Ready for use.

(00V) when a power failure occurs, the power source is switched to the storage battery 3, and then the voltage of the storage battery 3 drops and reaches a predetermined voltage,
Since the load 1 and the microcomputer 9 are shut off from the storage battery 3, the storage battery 3 will not consume power from discharging at that point. Therefore, even when the storage battery 3 is still loaded, it is possible to prevent the storage battery 3 from being over-discharged and leaking liquid, or being deteriorated in performance and life. As a result, the storage battery 3 and the load are insulated from each other or the storage battery 3 is connected to the equipment even when the commercial power supply is stopped for a long time, such as when the equipment is not used for a certain period at the time of shipment or with the power outlet disconnected. It is unnecessary to remove it more. Further, since a mechanism for attaching and detaching the storage battery 3, that is, a storage battery case in which the storage battery 3 can be easily attached and detached, is unnecessary, the lead wire 3a is welded to the power supply control unit 10 using the simple connector 3b and the tube pack is included. Batteries can be used. Further, when the heat source for cooking rice is gas, even if the commercial power source fails, the power source is switched to the storage battery 3 to perform combustion control, so that rice can be cooked without any trouble and is very convenient. Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the spirit of the present invention.

It is possible to prevent the liquid from leaking and the performance and life from being deteriorated. As a result, for example, even when the supply of commercial power is stopped for a long period of time, such as at the time of shipment or when the device is not used for a certain period with the power outlet disconnected, the storage battery is insulated from the device or the storage battery is connected to the device. It is unnecessary to remove it more. In other words, even if the storage battery is always loaded in the device, over-discharge is prevented, which is convenient. Moreover, the mechanism for attaching and detaching the storage battery is unnecessary.
